TO ALL WHOM IT MAY CONGERN:

Be it known that I, GEORGE R. GARDINEP., of lVesterly, in the county of Washington, and State of Rhode Island, have invented a new and improved Means for Depriving Wool, and other Fibrous Substances of Elec tricity during the Carding and Gondensing of the same; and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distinguished from all others ot' a similar class, together with such parts as I claim, and desired to have secured to me by Letters Patent.

In the manufacture of goods from wool, and some other iibrous substances, much dilculty is experienced by the development of electricity during the cardingr and condensing of the stock, or the forming of the same into ropings. The electricity thus developed very frequently deranges the condensing operation, causing the ropings to adhere to and wind around the cylinders of the condenser, and even the ropings, if they leave the condenser entire, are frequently broken by a strong current ot electricity, which passes around in front of the condenser. i

My invention consists in certain means employed for preventing the development of electricity during the earding and condensing operation, whereby a great amount of stock is prevented from being wasted, and the carding and condensing operation greatly expedited. In the accornpanyingsheet ot' drawings- Figure I is a side sectional view of a condenser provided with my invention, taken in the line z; 9;, iig. 2.

Figure 2, a horizontal section ot' the same, talien in the line y y, tig. I.

Similar letters ofV reference indicate like parts.

A represents the frame of a condenser, and B the cylinders thereof, These may be arranged in the usual or any proper manner, and therefore do not require a special description. C represents a hollow roller, constructed ot' thin` sheetinetal, and rotated by gears or a belt\t`iom any convenient cylinder of the condenser. The direction of the rotation of the cylinders and roller is indicated by the arrows in fig. I, the ropings, designated by a, passing from the front cylinders ot the condenser underneath the rollers G, and in Contact with the latter. Only one of these rollers C is shown in tig. I, but the upper cylinders I3 are t0 be supplied with one placed in the same relative position as the lower one, which is shown. These hollow rollers are supplied, say about two-thirds filled, with a composition consisting oi' fires-lay, orthnary briclqor potters clay, and granito dust, mixed with steel dust. The granite and steel dust may be obtained, mixed about in proper proportion, from' granite quarries, the dust from the drill-holes contmning the requisite amount of steel, which is worn off from the drills. The two different clays, and the granite and steel dust combined, are used in about equal proportions. These rollers C, charged with the compositi Yrnplesctibech effectunlly prevent the development oi' electricity; atleast nene is apparent to affect the ropings. which pass from the condenser without any impediment .vhatever.l D represents a frame, in which the cylinders E are placed, on which the ropings are wound. Guide-bars F are also placed onthis frame, haring metal staples or loops in thein, through which the ropings fz pass. These guide-burs are a short distance in front el" the condenser, and the ropings a are frequently much swayed or moved laterally by a strong current of electric' which passes around the front of the condenser, between it and frame D. rlhe end or outside ropings are most :ti'ected considerable embarrassment and loss of stock. In order to avoid this, I attach guards G to cago. guideer It, one near cach end ot' the same, said guards being cons.:ucted of sheet metal or other su le material, and placed in line with the ropings. These guards G serve to shield the ropings and break any currents of electrieity or draughts of air that may pass between the condenser and frame D,

I would-remark that instead of having the rollers il hollow, and Elled with the composition, they may be made solid, and the composition applied to their exterior, and secured or made to adhere thereto by any proper means. Either Way would answer equally well.

Having-thus described my invention, I claim as new, and desire to secure by Letters Patent I. The roller C, one or more, made either hollow or solid, and charged or covered with i' composition herein described, or its equivalent, and placed on a condenser, in relative position with thc cyli substantially in the manner as and for the purpose forth.

2. The guards G, attached to the guide-bars F en frame D, and arranged in relation with the repli-.gs a substantially as and for the purpose specified.
